基于J2EE和XML的构件库系统的设计

Design of Component Library System Based on J2EE and XML

为了解决构件存储在不同数据库中存在的访问和控制不便的问题,在研究构件描述、分类、表示的基础上,选择合适的开发技术,设计了基于J2EE和XML的构件库系统实现对构件的有效管理。采用刻面分类模式描述构件,用J2EE的分层体系结构来搭建,用XML语言来表示和存储构件,使构件的存储和使用脱离了数据库,完全基于Web实现,增强了系统的灵活性和跨平台性,为项目中其它模块的快速开发提供了保障,具有一定的理论和实践意义。

In order to resolve the problem of the components which are stored in different databases that exist the inconvenience in access and control,on the basis of the research of cornponent＇s description, classification and representation, choosed the right technology and designed a component library system based on J2EE and XML to manage the component effectively. Faceted classification model used to describe components, with J2EE structure of the system to set up, XML language used to express and store components, introduces a method fully based on web which can release the storage and use of components from the database, this will enhance the flexibility and cross - platform of the system and other projects fro the rapid development of the module provides protection. It also has a certain theoretical and practical significance.
